Overdraw application Overdraw GLFW3 Intel dmesg |

can you attach the source code and how to build it? Created attachment 114856 [details]
Overdraw application
I have fixed MIME for the overdraw demo. It requires Gtk+ 3.16 and it can be compiled by "clang main.c common/io.c `pkg-config --cflags --libs gtk+-3.0 epoxy`". Created attachment 114911 [details]
Overdraw GLFW3
This is a version using GLFW3 in case you do not have Gtk+ 3.16.
gcc common/io.c main.c `pkg-config --cflags --libs glfw3 epoxy`
Tesla card renders it correctly (it takes around 10 seconds), I will test on Intel (GL 2.1) when I get home. Intel x4500 hang too, but seems to do better job at reseting. Created attachment 114934 [details]
Intel dmesg
Hi Pavol, If the draw call takes more than 10 seconds, the kernel driver will consider it a hang and will try to reset the GPU, which might sometimes fail, leaving the GPU in an unusable state. I will close this as NOTABUG. Please try again with a lower instance count and make sure it finishes in 10 seconds. (In reply to Marek Olšák from comment #8) > I will close this as NOTABUG.

Created attachment 114845 [details] Demo Hi, by accident I found out that after some threshold on overdraw the GPU hangs. I have attached a simple program that demonstrates the problem.
